DM58 Preamplified Digital Microphone
Preamplified Digital Microphone
Analog or ARINC-429 Digital Output in the Cockpit
The L3Harris DM58 is a preamplified digital microphone that provides an ED-112A-compliant integrated Cockpit Area Microphone (CAM) and preamplifier functionality for commercial and military aircraft. The microphone output may be either analog for current generation Cockpit Voice Recorders (CVRs) or digital for next generation recorders. The inclusion of an ED-112A compliant preamplifier benefits customers by reducing system part count, size and weight.
